A possible idea for Ekko's ult
Okay, I want to start by saying that I think people pretty grossly exaggerate his OPness. I just got a petakill on him, because the entire enemy team dived me under my tower after I already set up my W, and my ghost was closing in. Then they proceeded to bitch about how OP the champ is and how I should have died. They acted like they didn't have an Ekko on their team as well lol.
Anyways, instead of having his ult deal damage, it could just give him a strong speed boost and reset all of his cooldowns. They may have to tweak the damage of his normal ability to make up for it (plus give a mana return); I am not sure. I don't think he actually needs this change, but it is one that I think would make the character more unique without nerfing him to the ground.
